Description

Technical Field

[0001] This utility model relates to the field of mixer technology, and more specifically, to a mixer with a spiral conveying mechanism. Background Technology

[0002] A mixer is a mechanical device that uses an internal stirring device to mix, stir, and grind materials. It is commonly used in industries such as chemical, pharmaceutical, food, and metallurgy. The main function of a mixer is to achieve thorough mixing of materials, improve reaction rates and product quality, and uniformly disperse loose solid materials. However, most existing mixers have their feed inlets located high up, making it inconvenient to put materials into the mixer and requiring other lifting equipment, resulting in poor usability. In addition, after the materials are mixed, it is not convenient to transport the mixed materials in the mixer to the intended subsequent processes. Therefore, we propose a mixer with a screw conveyor mechanism. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a mixer with a spiral conveying mechanism.

The output shaft of the third reduction motor 16 extends into the inner cavity of the stirring drum 1 and is fixedly connected to the stirring shaft 17 through a coupling. The bottom end of the stirring shaft 17 extends into the inner cavity of the discharge pipe 2 and is provided with a spiral conveying blade 20. The side of the spiral conveying blade 20 is in close contact with the inner wall of the discharge pipe 2 to ensure that the spiral conveying blade 20 can push the stirred material to fall smoothly. Multiple stirring rods 18 are fixedly connected to the side of the stirring shaft 17. An L-shaped scraper 19 is fixedly connected to the side of the stirring shaft 17. The outer side of the L-shaped scraper 19 is in close contact with the inner wall of the stirring drum 1.

[0018] Example 2: Based on Example 1, such as Figure 1 and Figure 4 As shown, the conveying mechanism 4 includes a discharge pipe 11 bolted to the bottom of the switch valve 3. A conveying pipe 12 is fixedly connected to the bottom end of the discharge pipe 11. A second reduction motor 13 is fixedly installed at the end of the conveying pipe 12. The output shaft of the second reduction motor 13 extends into the inner cavity of the conveying pipe 12 and is fixedly connected to a second spiral conveying rod 14 via a coupling.

[0019] Example 3: Based on Embodiment 1 and Embodiment 2, such as Figures 1 to 4As shown, a support ring 21 is fixedly sleeved on the outer side of the mixing drum 1. Multiple support legs 22 are fixedly connected to the bottom surface of the support ring 21. The support ring 21 and the support legs 22 support the mixing drum 1.

[0020] It should be noted that this utility model is a mixer with a spiral conveying mechanism. In use, firstly, the first reduction motor 10 is started to drive the first spiral conveying rod 9 to rotate, and the material to be mixed is placed into the inner cavity of the feeding hopper 8. The material falls into the inner cavity of the feeding pipe 7 under its own weight. The rotation of the first spiral conveying rod 9 causes the material to move upwards within the inner cavity of the feeding pipe 7, and the material that has moved to the top of the feeding pipe 7 is added into the inner cavity of the mixing drum 1 through the feeding pipe 6. Then, the third reduction motor 16 is started to drive the stirring shaft 17, stirring rod 18, L-shaped scraper 19, and spiral conveying blade 20 to rotate. The stirring rod 18 agitates the material inside the mixing drum 1, and the L-shaped scraper 19 agitates the material on the inner wall of the mixing drum 1. During the scraping process, the spiral conveyor blade 20 is in reverse rotation. The rotation of the spiral conveyor blade 20 drives the material in the inner cavity of the discharge pipe 2 to move upward. Then, after the mixing is completed, the switch valve 3 is opened, and the third reduction motor 16 is started to drive the stirring shaft 17, stirring rod 18, L-shaped scraper 19 and spiral conveyor blade 20 to reverse. The spiral conveyor blade 20 drives the material in the inner cavity of the mixing drum 1 to fall from the discharge pipe 2, switch valve 3, and discharge pipe 11 into the inner cavity of the conveying pipe 12. Finally, the second reduction motor 13 is started to drive the second spiral conveyor rod 14 to rotate. The second spiral conveyor rod 14 drives the material in the inner cavity of the conveying pipe 12 to move along the inner cavity of the conveying pipe 12, so that the mixed material moves to the equipment of the next process.
